Embodiment 1

[0015] First, the viscose fiber and wood pulp fiber are respectively opened and then placed in a fine pulverizer and mixed at a weight ratio of 25:75. The mixed fiber is transported to the sieve drum on the former by the separator. Under the condition of 60%, after the sieve drum and the nail rod are stirred at the opposite speeds of 40m / min and 100m / min respectively, the mixed fibers will pass through the elliptical holes on the sieve drum under the action of vacuum suction under the forming net. The paper web is formed by suction onto a forming wire under which the vacuum is 0.16 mbar.

[0016] The paper web is transferred to the spunlace machine through the transition net, pre-wetted first, and then spunlace is strengthened on the front and back sides in three steps. Among them, the spunlace pressure used during pre-wet is 30bar, and the speed of the web curtain or drum is 40m / Min, the first spunlace pressure is 40bar, the second spunlace pressure is 45bar, the third spunl...

Embodiment 2

[0029] First, the viscose fiber and wood pulp fiber are respectively opened and then placed in a fine pulverizer and mixed at a weight ratio of 45:55. The mixed fiber is transported to the sieve drum on the former by the separator. Under the condition of 75%, the mixed fibers are passed through the elliptical holes on the screen drum under the action of vacuum suction under the forming net after being stirred by the sieve drum and the nail rod in the opposite direction at speeds of 150m / min and 500m / min respectively. The paper web is formed by suction onto a forming wire under which the vacuum is 0.21 mbar.

[0030] The paper web is transferred to the spunlace machine through the transition net, pre-wetted first, and then spunlace is reinforced on the front and back sides in three steps, wherein the spunlace pressure used during the pre-wet is 60bar, and the speed of the web curtain or drum is 150m / Min, the first spunlace pressure is 80bar, the second spunlace pressure is 90b...

Embodiment 3

[0043] First viscose fiber and wood pulp fiber are respectively opened and then placed in a fine pulverizer and mixed with a weight ratio of 30:70, and the mixed fiber is transported to the sieve drum on the former, and the temperature is 27 ° C and the humidity is 70%. After being stirred by the sieve drum and the nail rod at the opposite speeds of 100m / min and 250m / min under the same conditions, the mixed fibers are absorbed by the elliptical holes on the sieve drum under the vacuum suction under the forming wire to the forming The web was formed on a wire with a vacuum of 0.18 mbar under the forming wire.

[0044] The paper web is transferred to the spunlace machine through the transition net, pre-wetted first, and then spunlace is reinforced on the front and back sides in three steps. Among them, the spunlace pressure used in the pre-wet is 45bar, and the speed of the web curtain or drum is 100m / min, the first spunlace pressure is 60bar, the second spunlace pressure is 60...

Abstract

The invention provides a method for producing moisture paper tissue material, which is characterized in that, the specific steps are as follows: opening viscose fiber and fluff pulp wood pulp fiber respectively, placing them into the fine pulverizer, and mixing them according to the weight ratio 25-45:55-75, producing mixed fiber into paper web with dry method of papermaking, carrying spunlace reinforcement, and then drying for obtaining moisture paper tissue material.

Description

technical field [0001] The invention relates to a method for manufacturing a novel wet tissue material, which belongs to the technical field of wet tissue materials. Background technique [0002] At present, domestic wet wipe products mostly use spunlace nonwoven materials. Spunlace nonwoven materials have the advantages of soft texture, comfortable hand feeling, good drapability, no chemical adhesives, good air permeability, fast production speed and high production capacity. However, at present, viscose and polyester are mainly used as raw materials in China's spunlace nonwoven process, which are non-degradable and cannot be washed away by toilet water, which is inconvenient to handle and has a poor hand feel. [0003] Dry-laid papermaking technology, also known as pulp air-laid technology, is a new method of producing non-woven fabrics through air-laid and different consolidation methods using wood pulp fibers as the main raw material. Because the fiber used in this met...
